-This f invention relates I to cloth-winding for re-winding into another package, and is 5 intended to providea simple and convenient construction. for 1 mounting and 'rotatably supporting a bolt of cloth for the unwinding part=of the operation.

Bolts of cloth are commonly wound ona thin, fiat core-board of Wood, paste-board or the like, and oftentimes this core-board has not sufiicient stillness or'rigidity to'sup I port the endwise grip of chuck jaws that have beenheretofore'used in" this class of devices. Furthermore, oftentimes bolts {of cloth are put- 11p"without-"any; permanent core-board so that there is'no' core-board to be gripped b the gripp'ingjaws'o-fa hold:

ing chuck. t has also been-proposed'to in sert, lengthwise through the cloth bolt, a

. longitudinal shaft or rod carrying fins or web sat each end, butsuch devicesfre'quire not only great care in making the insertion but even-then are very likely to tear and in- '25:; j e delicate fabrics;

With? the object of overcoming these difficulties the present invention comprisesa pair of entirely separate aligned stub shafts held "in fixed position at a-nydesired distances apart, and carrying at their inner ends freely rotatable cloth-bolt engaging and supportwill be'particularly explained in the following members. comprising thin, v triangular blades, each converging to an apex at its inner end so as to taper to a thin point which are easily inserted between the core-board and the cloth wound thereon up toa point where the diverging side edges engage the inside layer of cloth.

These and other'features of this invention ing specification and will be described in the claims hereto annexe While this unwinding reel is adapted for use in re-winding machines, clotl1-measuring machines and the like, it will suffice, for an understanding of the invention, to show the same mounted in a separate frame or horse,

that are shown in'the drawings, comprise trlangular blades6 havingtheir sides equah ly converging toward'the apex at the inner end, and preferably also tapered transversely to provide a thin point or apexeasilyinsertable inside the cloth-bolt. I

iSometimesit maybe desired to produce a slight retardation orfriction and to provide for such a contingency I have provided theh-ub or bearing member 5 with an axialotally. mounted clamping jaws 9, which-may be drawn together, into frictional engagement with the stub-sha-ft toproduce any de sired degree of friction. A thrust spring 9 tends to ,yieldingly thrust the armsi apart when they are not clampedagainst the shaft:
